Transaction processor for clearing interest rate swaps with improved efficiency

ABSTRACT

The disclosed embodiments relate to improving the efficiency of an electronic trading system for interest rate swaps (“IRS”) by allowing for IRS contracts to be funded in a base currency while the cash flows, e.g. coupon payments, price alignment interest, variation margin, are denominated in a local currency different from the base currency. Thereby cash flows may be netted and offset minimizing the magnitude of funds needed to be moved and reducing the number of transactions processed by the electronic trading system as well as the consumption of computational resources thereby. Furthermore, the disclosed embodiments facilitate entering into IRS transactions is a currency different from the currency of cash flows while eliminating Herstatt risk due to volatility of foreign exchange rates, which allows for increased off shore participation and thereby increased transaction volume.

BACKGROUND

A financial instrument trading system, such as a futures exchange, referred to herein also as an “Exchange”, such as the Chicago Mercantile Exchange Inc. (CME), provides a contract market where financial instruments, for example futures and options on futures, are traded. Futures is a term used to designate all contracts for the purchase or sale of financial instruments or physical commodities for future delivery or cash settlement on a commodity futures exchange. A futures contract is a legally binding agreement to buy or sell a commodity at a specified price at a predetermined future time. An option is the right, but not the obligation, to sell or buy the underlying instrument (in this case, a futures contract) at a specified price within a specified time. The commodity to be delivered in fulfillment of the contract, or alternatively the commodity for which the cash market price shall determine the final settlement price of the futures contract, is known as the contract's underlying reference or “underlier.” The terms and conditions of each futures contract are standardized as to the specification of the contract's underlying reference commodity, the quality of such commodity, quantity, delivery date, and means of contract settlement. Cash Settlement is a method of settling a futures contract whereby the parties effect final settlement when the contract expires by paying/receiving the loss/gain related to the contract in cash, rather than by effecting physical sale and purchase of the underlying reference commodity at a price determined by the futures contract, price.

Typically, the Exchange provides for a centralized “clearing house” through which all trades made must be confirmed, matched, and settled each day until offset or delivered. The clearing house is an adjunct to the Exchange, and may be an operating division of the Exchange, which is responsible for settling trading accounts, clearing trades, collecting and maintaining performance bond funds, regulating delivery, and reporting trading data. The essential role of the clearing house is to mitigate credit risk. Clearing is the procedure through which the Clearing House becomes buyer to each seller of a futures contract, and seller to each buyer, also referred to as a novation, and assumes responsibility for protecting buyers and sellers from financial loss due to breach of contract, by assuring performance on each contract. Essentially, the transaction between the buyer and seller is bifurcated into two separate transactions, one between the buyer and the Clearing House and another transaction between the seller and the Clearing House. These transactions are not dependent on each other. That is, as the Clearing House guarantees performance to either party, should the buyer or seller default or otherwise fail to perform their obligation under their transaction with the clearing house, the other party's transaction remains unaffected. The Clearing House protects itself from loss by requiring each party to post a performance bond to cover the potential risk of loss of that party to the Clearing House. As any given party's risk of loss may change over time, going up or down, the Clearing House further periodically, e.g. daily, calculates adjustments to the risk of loss and the performance bond, referred to as “variation margin”, and credits or debits the party accordingly. A clearing member is a firm qualified to clear trades through the Clearing House for itself, referred to as production trades, or on behalf of their customers.

An interest rate swap is a well-known financial transaction typically occurring between two parties. In a swap, the two parties agree to make payments to each other; the payments of the first and second parties define the type of swap. In a basis swap, the payments made by the first and second parties are based on different floating interest rates in the same currency. In a currency swap, the payments are made based on either fixed and/or floating interest rates in different currencies. In an interest rate swap, the payments made by the parties are in the same currencies, but one of the payments is based on a fixed interest rate while the other payment is based on a floating interest rate. The two parties to the interest rate swap are called counterparties.

One purpose of an interest rate swap is as a hedge from changing interest rates; however, such hedge results in an added cost. In an interest rate swap, while one party is often hedging against potential losses, the other party is often seeking financial gain based on speculation that the added cost paid by the hedging party will be greater than the actual change in value due to the interest rate change.

The payments made between the parties in an interest rate swap are based on interest rates; however, the interest rate is only one factor in determining the amount of payment. Another factor is the amount of principal which is periodically multiplied by the different interest rates to determine the payments made. In an interest rate swap, there is no exchange or payment of principal, so the principal is referred to as being a notional amount. This notional amount dictates the size of the interest payments and is agreed on by the parties when negotiating the terms of the interest rate swap. The notional amount remains constant for the duration of the swap.

For example, an exemplary interest rate swap could be between a first dealer (for example, a typical bank which is relatively small in size) which desires to reduce the risk of interest rate fluctuation and a second dealer (for example, a large financial institution) which is willing to accept a risk in interest rate fluctuation in return for receiving a higher fixed interest rate. The first dealer agrees to pay the second dealer interest payments that are based on a long term fixed rate. In exchange, the second dealer agrees to pay the first dealer interest payments that are based on a short term floating rate. Thus, the first dealer and the second dealer are counterparties.

Typically, the floating interest rate is tied to the London Interbank Offered Rate (LIBOR), which is the rate of interest at which banks can borrow funds from other banks, in marketable size, in the London Interbank market and is set by the British Bankers' Association, Pinners Hall, 105-108 Old Broad Street, London EC2N 1EX United Kingdom, a trade association representing banks and other financial services firms that operate in the United Kingdom. If the first dealer and the second dealer enter into a swap over a longer-term period (for example five (5) years), the first dealer pays out interest to the second dealer according to the fixed rate over that period (e.g. five years at the five-year fixed rate) and receives interest from the second dealer according to a floating shorter-term rate (for example, the three-month LIBOR rate) over that same period. Conversely, the second dealer receives interest payments from the first dealer according to the fixed long-term rate and pays interest payments to the first dealer based on the floating short-term rate. Both the fixed long-term rate and the LIBOR rate are applied to a common notional principal. Alternatively, both series of cash flows could be based on different floating interest rates, that is, variable interest rates that are based upon different underlying indices. This type of interest rate swap is known as a basis or a money market swap.

Before entering into an interest rate swap contract, the first dealer and the second dealer may try to value the price of the interest rate swap. The value of an interest rate swap is the difference between the net present value of the two future income streams that are swapped by the first dealer and the second dealer. Because the floating interest rate varies in the future, the size of each future cash flow based on the floating interest rate is not known to either the first dealer or the second dealer. To solve this problem, the swap market uses forward implied interest rates to estimate the net present value of the fixed and floating interest rates. The forward interest rates may be derived from convexity adjusted Eurodollar Futures rates for example, or benchmark swap rates promulgated by the International Swap Dealers Association (ISDA) 360 Madison Avenue, 16th Floor, New York, N.Y. 10017 USA, a global trade association representing participants in the privately negotiated derivatives industry. The ISDA also provides a legal master documentation for interest rate swap transactions (available at http://www.isda.org/cl.html). ISDA agreements are essential for each new counterparty, and amendments to agreements are required for each new deal with a particular counterparty.

Thus, an interest rate swap is effectively a construction of two cash flow streams with the same maturity. In a “vanilla” fixed for floating interest rate swap one of the cash flow streams is comparable to that of a bond (fixed interest rate payments) and the other cash flow stream is comparable to a periodically revolving borrowing/lending facility or floating rate note (floating interest rate payments). Mathematical analysis shows that the net present value of an interest rate swap has interest rate sensitivity similar to the price of a bond having a similar coupon, maturity, and credit rating.

The similarities between in the interest rate sensitivities of “vanilla” interest rate swaps and bonds explains the heavy use of government bond futures, government bond repos, and the cash market to manage interest rate risk resulting out of interest rate swap transactions; this practice, however, also involves disadvantages. Initially, both market segments are based on different credits and therefore an unexpected change in the yield differential of the two markets could result in heavy losses. In addition, conventional techniques require efficient access to the bond and repo market. Specifically, repo transactions can be problematic since these transactions have to be renegotiated on a regular basis and market conditions can be volatile.

An interest rate swap (“IRS”) is a contractual agreement between two parties, i.e., the counterparties, also referred to as the payer and receiver, where one stream of future interest payments is exchanged for another, e.g., a stream of fixed interest rate payments in exchange for a stream of floating interest rate payments, based on a specified principal amount or an assumed notional amount. An IRS may be used to limit or manage exposure to fluctuations in interest rates. One common form of IRS exchanges a stream of floating interest rate payments on the basis of the 3-month London interbank offered rate (“LIBOR”) for a stream of fixed-rate payments on the basis of the swap's fixed interest rate. Another common form of IRS, known as an overnight index swap, exchanges, at its termination, a floating rate payment determined by daily compounding of a sequence of floating interest rates on the basis of an overnight interest rate reference (e.g., the US daily effective federal funds rate, or the European Overnight Index Average (EONIA)) over the life of the swap, for a fixed rate payment on the basis of daily compounding of the overnight index swap's fixed interest rate over the life of the swap.

The components of a typical IRS may be defined in a swap confirmation which is a document that is used to contractually outline the agreement between the two parties. The components defined in this agreement may include:

-   -   Notional—The fixed and floating coupons are paid out based on         what is known as the notional principal or just notional. If one         were hedging a loan with $1 million principal with a swap, then         the swap would have a notional of $1 million as well. Generally         the notional is never exchanged and is only used for calculating         cash flow amounts;     -   Fixed Rate—This is the rate that will be used to calculate         payments made by the fixed payer. This stream of payments is         known as the fixed leg of the swap;     -   Coupon Frequency—This is how often coupons would be exchanged         between the two parties, common frequencies are annual,         semi-annual, quarterly and monthly though others are used such         as based on future expiry dates or every 28 days. In a vanilla         swap the floating and fixed coupons would have the same         frequency but it is possible for the streams to have different         frequencies;     -   Business Day Convention—This defines how coupon dates are         adjusted for weekends and holidays. Typical conventions are         Following Business Day and Modified Following;     -   Floating Index—This defines which index is used for setting the         floating coupons. One common index is LIBOR. The term of the         index will often match the frequency of the coupons. For         example, 3 month LIBOR would be paid Quarterly while 6 month         LIBOR would be paid Semi-Annually;     -   Daycount conventions—These are used for calculating the portions         of the year when calculating coupon amounts;     -   Effective Date—This is the start date of a swap and when         interest will start accruing on the first coupon; and     -   Maturity Date—The date of the last coupon and when the         obligations between the two parties end.

Currently, most IRS's are entered into on a bilateral, principal-to-principal basis, i.e. outside of an exchange (referred to as “over the counter” or “OTC”) with each ultimate counterparty being the entity with whom the other party executed the trade. As opposed to trades, such as trades in futures contracts, which are cleared via a clearing house, as described above, OTC derivatives may be booked bilaterally between the counterparties, as opposed to cleared derivatives which are booked with a clearing house. OTC bilateral derivatives counterparties, such as those involved in a IRS agreement, therefore assume credit exposure, known as counterparty credit risk, to each other while cleared derivatives counterparties are exposed to credit risk of the clearing house. Second, cleared derivatives always involve the posting of margin to the clearing house by the parties to a trade, while margining by OTC bilateral derivatives counterparties is subject to negotiation by the parties. Finally, the terms of OTC bilateral derivatives can be customized to fit the needs of the contracting parties. The terms of cleared derivatives, in contrast, typically involve a high degree of standardization to facilitate the computation of required margin amounts.

Within the interest rate swap market, bilateral netting agreements facilitate netting of positions between specific counterparties by reducing credit exposure and freeing up capital; however, it is difficult, if not impossible, for participants to freely net deals across multiple counterparties. Further, it is time consuming and cumbersome to settle each agreement separately, and there is no guarantee that the cancellation or assignment of a particular contract provides the best price.

Central clearing is designed to standardize certain swaps, promote transparency, and allow market participants to mitigate their counterparty credit risk to dealers. Accordingly, it is advantageous to centrally clear OTC IRS's.

DETAILED DESCRIPTION

The disclosed embodiments relate to improving the efficiency of an electronic trading system for interest rate swaps (“IRS”) by allowing for IRS contracts to be funded in a base currency while the cash flows, e.g. coupon payments, price alignment interest, variation margin, are denominated in a local currency different from the base currency. Thereby cash flows may be netted and offset minimizing the magnitude of funds needed to be moved and reducing the number of transactions processed by the electronic trading system to effect those cash flows as well as the consumption of computational resources thereby. Furthermore, the disclosed embodiments facilitate entering into IRS transactions is a currency different from the currency of cash flows while eliminating Herstatt risk due to volatility of foreign exchange rates, which allows for increased off shore participation and thereby increased transaction volume.

As discussed above, an IRS generally consists of a contractual agreement between two parties, i.e., the counterparties, also referred to as the payer and receiver, where one stream or series of future interest payments is exchanged for another, e.g., a stream/series of fixed interest rate payments in exchange for a stream/series of floating interest rate payments, based on a specified principal amount or an assumed notional amount. The payments are referred to as “coupons.” In a plain IRS contract, as opposed to a cross-currency swap, both series of payments occur in a single currency, e.g. dollars, Euros, etc., which is specified by the IRS contract, and generally, the party making a particular payment funds that payment in the requisite currency. However, in certain situations, as will be described in more detail below, a party may desire to fund their payment in a different currency then required by the IRS contract and will therefore need to convert their funding to the requisite currency in order to make the payment and satisfy their obligation under the IRS agreement, e.g. they will have to buy, using their base currency, the requisite amount of the local currency that they need per the contract. Similarly, a party may desire to receive a payment owed in a currency different from the currency specified in the IRS contract and will therefore need to convert the received payment to their desired currency upon receipt, e.g. sell the local currency in exchange for their base currency. As the process of paying and receiving a coupon payment, as well as the conversion between currencies, is not instantaneous, changes in the rate of exchange between currencies presents a risk to either party until the transaction is completed. This is referred to as Herstatt risk. Herstatt risk, also known as cross-currency settlement risk or foreign exchange risk is the risk that a party to a trade fails to make payment even though it has been paid by its counterparty.

As was discussed above, it is desirable to clear OTC IRS contracts in order to standardize certain swaps, promote transparency, and allow market participants to mitigate their counterparty credit risk to dealers. Clearing introduces additional complexities related to the mitigation of risk. In particular, in order to protect the clearing organization/central counter party (“CCP”), the CCP will require each party to an IRS to post a performance bond to cover their risk of loss. As the value of each party's position in an IRS may vary day to day as interest rates change, the CCP will adjust the amount of the performance bond as the risk of loss changes, requiring that one party post additional funds or receive a credit of funds previously posted. This is referred to as variation margin. Both the initial performance bond and the variation margin are based on the present value of the IRS. To value an IRS, the total value of all remaining fixed and floating coupon payments is determined and then discounted to create a net present value of that total amount. To assess the value of the remaining floating payments, a forecast curve is used which predicts, estimates or implies the value of the floating interest rate at each of the future payment dates. To determine the net present value of the fixed and floating payments, a discount curve is used which predicts, estimates, or implies prevailing future interest rates.

Once computed, the performance bond and subsequent variation margin is credited to, or collected from, each of the party and counter party to the IRS. While these funds are collected/paid with respect to the CCP, generally one party to the IRS benefits at the expense of the other party as the value of the IRS varies. To compensate for the burden of posting margin, the CCP may implement Price Alignment Interest. Price Alignment Interest (“PAI”) is the overnight cost of funding collateral. It is debited from the receiver and transferred to the payer to cover the loss of interest on posted collateral, i.e. variation margin. As described above, as the value of the floating leg of an IRS varies over the life of the IRS, the net present value (“NPV”) will change resulting in variation margin (“VM”) being credited to one party and required/collected from the other party. PAI transfers the benefit of receiving VM back to the payer of the VM. PAI then is the overnight cost of funding the VM, debited from the receiver and transferred to the payer. PAI is generally not required for futures contracts, i.e. for a Futures trade, generally because the rules of a CCP typically define that each day the closing price of the contract is used to calculate VM, and the profit or loss is debited from the party's margin account daily. The exchange/CCP may regard this payment as full and final settlement of the contract, as should the counterparty default, the party will receive no further payment on this contract. This means a Futures trade is regarded as “final” or “matured” on each and every day, until the expiry date of the contract, in which case the VM payment is a settled amount, and not a margin asset. Accordingly, in this case, the receiver of VM are free to re-use any VM payment, as in the example above, without the PAI adjustment.

For an OTC IRS trade, the VM payment represents the value of future cash flows, which remain unsettled until each coupon date, and final maturity, so one may regard VM as an amount of margin which they would receive back should the value of the contract move in their favor. The difference in default, is that in some CCPs for OTC products, the portfolio of trades owned by the defaulting party (for direct members) are auctioned, such that eventually a new party takes ownership, and the contract continues unchanged until maturity. This means the VM payment for an OTC IRS trade is characterized as a margin asset, which one would expect not to lose should their counterparty default, hence the application of PAI, equivalent to receiving interest on this margin asset, is applied.

Should PAI be ignored by a CCP, the payer of VM would feel the penalty of clearing, which they wouldn't outside a CCP. PAI evens this out to some degree.

Accordingly, during the life of a cleared OTC IRS, there are several types of cash flows which occur, the coupon payments, the variation margin and the PAI. When computing variation margin and PAI, accurate computation of the net present value of the IRS's remaining coupon payments is important. Where the parties will fund these coupon payments in the same currency as required under the IRS, the valuation calculation merely requires appropriate forecasting and discounting curves for the appropriate interest rates in the home country of the currency. However, where the parties are funding their payments in a different currency then required under the IRS contract, the exchange rate between their desired currency and the requisite currency can affect the valuation of the IRS contract. Parties may wish to fund an IRS contract in a different currency, referred to as the “base” currency, then the currency required under the contract, referred to as the “local” currency, when, for example, the market for such IRS contracts is greater outside of the home country of the local currency. The currencies for which IRS contracts most heavily trade are referred to as the G17 currencies (as there are 17 currencies on this list) and includes dollars, Euros, Yen, Canadian Dollars, etc. Non-G17 currencies include, for example, Mexican Pesos.

Furthermore, in cleared OTC IRS trades, it is desirable that all of the cash flows, e.g. coupon payments, VM and PAI, occur in the same currency. This permits these cash flows to be netted or otherwise offset against each other which may reduce the magnitude, as well as simplify the computation, of the value to be moved among the parties the CCP, reduces the number of transactions to effect the cash flows where a particular cash flow is completely offset (effectively eliminating the need for the transaction), and lowers Herstatt risk as the CCP need not enter into any currency exchange transactions when facilitating the cash flows among the parties and the CCP. Reduction in transactions to effect the cash flows is particularly advantageous as it may correlate to a reduction in the consumption of computational resources and processing capacity allowing for increased transaction volume handling.

In order to clear OTC IRS trades which are funded in a base currency different from the local currency in which the cash flows occur, accurately valuing the IRS for calculation of VM, PAI, etc. requires accounting for the differences between the base and local currencies, while maintaining the resultant valuation denominated in the local currency such that the cash flows are all in the same currency.

As was discussed above, in order to value an IRS, the present value of cash flows of each leg of the transaction must be determined. In an IRS, the fixed leg is fairly straightforward since the cash flows are specified by the coupon rate set at the time of the agreement. Pricing the floating leg is more complex since, by definition, the cash flows change with future changes in the interest rates. The projected floating payments are based on the estimated yield curve of a market index rate, e.g. LIBOR, US Fed Funds, as of the measurement date, which is derived by bootstrapping the index's spot yield curve. Bootstrapping is a method utilized to construct a fixed-income yield curve using forward substitution whereby quoted periodic spot rates are used to estimate future spot rates based on a “no arbitrage” principal. The projected future cash flows are then discounted to a present value using a discount curve, i.e. discount factors for different maturities. Accordingly, two curves are necessary for valuing an IRS, a forecast curve, which accounts for future changes in the interest rate, used to value the cash flows of the floating leg and a discount curve used to calculate the net present values of the cash flows of the fixed and floating legs, the sum of which is the current value of the IRS. For IRS's denominated in one of the G17 currencies, such forecast and discount curves are well known and are based on well known indices for those currencies, e.g. LIBOR for Euros, US Fed Funds rate for dollars.

However, using these curves works well only when the IRS to be valued is funded in the same currency as the cash flows being exchanged. In other words, when an IRS having cash flows denominated in a local currency, e.g. Pesos, is funded in another base currency, e.g. dollars, using standard forecasting and discount curves based on local currency indices does not account for volatility in exchange rates between the local currency and the base currency. That is, a trader wishing to transact in local currency IRS's will first need to convert their funding from the base currency to the local currency prior to entering into such a transaction. Similarly, as they pay or collect payments according to the IRS terms, they will need to convert those payments between the local and base currency. In each situation, the trader (or their counter party) is exposed to risk due to volatility in exchange rates, referred to as Herstatt risk. As such contracts are typically entered into when there is a larger off-shore market for the IRS in the local currency than in the local/on-shore market, traders desire to transact in their home/base currency rather than in the local currency. To minimize risk due to exchange rate volatility, the disclosed embodiments utilize forecasting and discount curves which account for this volatility. This allows a party to an IRS to value the IRS in the local currency while accounting for the base currency. Such curves may essentially factor the exchange rates between the base and local currencies predicted to be prevailing at the time of each coupon payment. For example, a standard forecast curve based on the floating rate index and a standard discount curve based on the local currency institutional interest rats may be modified based on forecasted exchange rates derived from the foreign exchange market and/or cross-currency swap agreements for the local/base currencies taken from the swaps markets to provide discount and forecast curve values for the different tenors of the IRS contract.

In building these forecast and discount curves, for example, three instruments may be used as inputs, a “vanilla” IRS funded and denominated in the local currency, a local/base currency exchange forward contract and a local/base cross currency swap contract. For example, the vanilla IRS funded and denominated in the local currency may include the MXN TIIE Swap. The MXN TIIE Swap is a vanilla interest swap, the payment frequency is “28-day” month and the floating index referred to is the 28-day TIIE rate, which is the main interbank reference rate and calculated on a daily basis. TIIE Swaps serve as curve inputs for both discount and forecast curves. The local/base currency exchange forward contract may include the USD/MXN FC Forward contract wherein the FX Forward outright rate is calculated as the interest rate differential between Mexican Peso and US Dollar, using the interest rate parity. The local/base cross currency swap contract may include the USD/MXN Cross Currency Swap wherein the TIIE-Libor cross currency swap involves an exchange of floating rates in USD Libor 1M and MXN TIIE 28 Day. The quotation represents the basis points that are used as spread over Libor as equivalent to THE. In constructing the discount curve, such as for Mexican Pesos, from 0 up to 1 year, FX forward is used for the calculation of MXN discount curve. To cover longer tenor, TIIE-USD Libor 1M cross currency swap is employed, since liquidity of FX forward drops beyond 1Y. There are two curves taken as prerequisite for the MXN discount curve, which is USD Fed Funds Curve and USD Libor 1M curve. Those two curves are taken as foreign discount and forecast curve respectively. The forecast curve for Pesos may then be derived from the discount curve.

The disclosed embodiments may be used for implementing cleared IRS's funded in a base currency but with cash flows denominated in local currencies, e.g. where those IRS contracts are not widely traded in the local market, i.e. the country of the local currency, but instead are more widely traded in off-shore markets, i.e. the country of the base currency. It will be appreciated then that the disclosed embodiments may be utilized where the local and base currencies are any two different currencies, including those currencies which are used in more widely traded IRS contracts, e.g. typically those in the top 17 currencies, commonly referred to as the “G17”, where there are substantial markets. However, in the typical case, the disclosed embodiments will be more likely used when the local currency is a lesser trader currency, e.g. a non-G17, currency. As such, the disclosed embodiments will be described with respect to exemplary IRS contracts denominated in Mexican Pesos (“MXN”) but funded, or otherwise valued/collateralized in U.S. dollars (“USD”). While a bilateral MXN (non-cleared) IRS exists, a Cleared MXN IRS product does not exist in the marketplace that takes into account the off shore funding impact, the clearing process and cash flow movements into valuation. However, it will be appreciated that the disclosed embodiments are applicable to any cleared IRS denominated in a deliverable local currency, i.e. the cash flows (coupon payments, variation margin and PAI) occur in the local currency, but funded or otherwise collateralized/valued in a base currency different from the local currency, and in particular where the local currency is considered a non-G17 currency and the base currency is a G17 currency.

Specifically, the disclosed embodiments address the situation where the funding (collateral) for the swap instrument is in a different currency than the cash flows such as variation margin, coupon payments, and PAI. For example, the USD-MXN swap is funded in USD, but the cash flows are in MXN Peso. This example and the examples below use the USD-MXN Peso swap as an illustration, but the new method can be used for any deliverable currency outside of the G17 currencies.

As described above, it is not desirable to require market participants to fund such a cleared swap at an “offshore” (U.S.-based) clearing house with the “local” (in this case, MXN Peso) currency. It is also problematic to administer daily cash flows in the offshore currency because the PAI of the offshore currency will be subject to different overnight rates.

The disclosed embodiments provide a new mechanism for pricing cleared currency swaps which takes into account a conversion between USD and MXN Peso while still funding the instrument in USD and administering the daily cash flows in MXN Peso. In one embodiment, this mechanism employs the following steps:

-   -   1. MXN Swaps are priced using a USD funding. The MXN discount         curve will take into account USD Overnight Index Swap rate         (“OIS”) and USD MXN basis and used to determine a MXN Net         Present Value (“NPV”).     -   2. For the MXN Peso, moving coupon payments are a contractual         obligation, so all cash flows such as variation margin, coupon         payments, and PAI will move in MXN Pesos.     -   3. USD funding is used for pricing, so the mechanism relies on a         “fed fund” rate to compute the equivalent PAI amount using the         following steps:         -   a. Cumulative variation margin (“VM”) is determined in             Pesos;         -   b. The method converts the VM to USD using the relevant             foreign exchange (“FX”) rate (FX0);         -   c. Using the USD VM number from (b) and the Fed Funds rate,             the PAI amount is computed in USD; and         -   d. The USD VM and PAI amount are both converted back to             Pesos using the relevant FX rate (FX1)

Note that the FX rate mentioned in steps 3 b and 3 d will be slightly different. FX0 is the cash FX rate at time T and FX1 is the FX rate for time T+1. FX0 is the FX overnight rate and FX1 is tomorrow's rate. These are the first two points used to construct the USDMXN cross-currency basis curve.

The steps above can also be accomplished by creating a MXN PAI rate which will be the Fed Funds rate adjusted by the FX0/FX1 rates as follows:

Overnight indexed swaps are interest rate swaps in which a fixed rate of interest is exchanged for a floating rate that is the geometric mean of a daily overnight rate. The calculation of the payment on the floating side is designed to replicate the aggregate interest that would be earned from rolling over a sequence daily loans at the overnight rate. In U.S. dollars, the overnight rate used is the effective federal funds rate (the federal funds rate is “the interest rate” at which depository institutions actively trade balances held at the Federal Reserve, called federal funds, with each other, usually overnight, on an uncollateralized basis. Institutions with surplus balances in their accounts lend those balances to institutions in need of larger balances. The interest rate that the borrowing bank pays to the lending bank to borrow the funds overnight is negotiated between the two banks, and the weighted average of this rate across all such transactions is the federal funds effective rate.). The “risk-free” term structure of interest rates is a key input to the pricing of derivatives. It is used for defining the expected growth rates of asset prices in a risk—neutral world and for determining the discount rate for expected payoffs in this world. Many banks now consider that overnight indexed swap (OIS) rates should be used as the risk—free rate when collateralized portfolios are valued.
